Hey Tyler, thanks for reaching out. I'm sorry to say no, we don't have a 5 on 4-1/2" hub, or any hub for that matter that fits a 3/4" straight spindle. That kind of spindle was really only seen on older trailers and is basically obsolete nowadays. The only straight spindle hubs we have are for a 1" or 1-1/16" spindle.

It's probably going to be very difficult if not impossible to find a hub for that spindle. At this point I'd recommend looking at replacing the axle with something more standard. We may have an axle for you; we would just need to look at the hub face length and spring center length of the current axle so we can match that up.

For example, the CE Smith Trailer Axle Beam with Studded Hubs # CES84XR comes with 5 on 4-1/2" hub and is sized for a 40" frame. It has a 49-1/2" HF and 38-7/16" SC. Its 54" long overall which is a pretty common size for smaller boat or jetski trailers.

If you want to measure that and shoot me that info I'm happy to look into it and see if we have anything.
